threshold = False

counts([axis])

Count number of photons or clicks.

counts(axis=1)

Count number of photons or clicks.

Counts number of photons/clicks in each sample (axis==1) or number of photons/clicks in each mode compounded over all samples (axis==0).

Parameters

axis (int) – axis to perform count

Returns

counts from samples
